Call Quality and CLI testing

Integrated call testing service

Automated Call Testing facility is designed to simplify Carrier route testing, route quality monitoring, FAS detections and
to verify correct CLI delivery.

Users can perform various tests using one or multiple suppliers, automate testing scenarios and be informed by email when quality drops or False Answer Supervision (FAS) is detected. R&R is using advanced voice recognition algorithms to detect the following cases:

  • Connect while ringing
  • Silence after connect (Dead Air)
  • Known IVR patterns
  • Lack of audible ringback tone

Call Testing Facility records media, counts media packets exchanged in both directions and calculates Mean Opinion Score (MOS) for the test call.

User is able to listen to each test call to have own opinion about the voice quality
